Rafal Posted July 9, 2002 Share Posted July 9, 2002 Hi all Howto assign a different material/shader to each metaballs. I'm using a copy SOP a switch SOP and I'm switching randomy using $PT in copy SOP 2 type of material. When I render this I don't see this 2 material. I tried this with usual geometry : poly or nurbs. It works fine. Is there a difference. Quote Link to comment Share on other sites More sharing options...
Jason Posted July 10, 2002 Share Posted July 10, 2002 I'll guess that mantra has no support for the blending of the shaders which should happen when two metaballs with different shaders are merged. Mantra would have to evaluate the surface and displacements for each shader and then blend the results and knowing mantra, thats actually harder than it sounds. I don't think you'll find many open renderers these days, (prman, entropy, renderdotc, mental ray) that'll do this for you automatically - from *any* package. If the render doesnt have true displacement mapping then it's much easier to do. I think you'd have to write a custom shader that computed both results and then you blend them yourself. Not the answer you want to hear, but this will be a lot easier in 5.5. Cheers, Jason Quote Link to comment Share on other sites More sharing options...
Rafal Posted July 10, 2002 Author Share Posted July 10, 2002 So I inpossible in houdini due to color blending. It only works with typical geometry. Are sidefx will implement that in 5.5, will be there any new features? I'm intersing what is your opinion about output to MR? Quote Link to comment Share on other sites More sharing options...
